Description

For the AR builder looking for the perfect combo of quad rail handguard on a rifle chambered in .300BLK, check this out. Our complete .300 AAC blackout rifle build kit features a quality heavy barrel made from 4150 chrome moly steel and carbine-length quad rail picatinny handguard, housing a low-profile, carbine-length gas system. This unique setup allows you to easily switch from supersonic to subsonic loads without the need to swap gas systems or barrels. The simple but proven quad rail offers plenty of space to mount attachments like tac lights, lasers, etc.

Mil-Spec Built, 1-MOA Accuracy on a Budget

Even though our .300 AAC blackout build kit is affordable, it isn't cheap. The whole thing's built with mil-spec ratings and features, including a gold-standard 4150 chrome moly barrel that promises 1 MOA of accuracy at 100 yards, M4 feed ramps, M4 flat top upper receiver, A2 birdcage flash hider, and of course, a near replica of the military's tried and true KAC RAS quad rail system. Unlike the military's though, our quad rail is free-floating, which provides more accuracy than a fixed handguard. Plus, everything is made here in the USA to ISO 9002 quality control standards.

Please note:This AR-15 Build Kit requires that the builder completes the 80% lower receiver themselves, but that’s the fun part (and the only way to build your own AR-15 without the need of an FFL transfer or serialization).

BEST **** FOR THE BUCK!

This is my first AR that I've owned and I didn't have a lot of money, so I went with this because of the price and I have to say that this thing functions INCREDIBLY well for the price! Very easy to assemble and finish. Definitely a great place to start my AR journey!
